A braking system in an at least partially autonomous vehicle, having one vehicle wheel brake per vehicle wheel and having a primary brake regulation system and a redundant secondary brake regulation system. One hydraulic actuator for actuating the vehicle brake is provided per vehicle wheel in a first vehicle axle which actuator is assigned to both the primary brake regulation system and also the secondary brake regulation system. One electromechanical primary actuator per vehicle wheel is assigned to the primary brake regulation system in the second vehicle axle and one electromechanical secondary actuator is assigned to the secondary brake regulation system.

Braking system for an autonomous vehicle

A method for determining potential damage to a vehicle battery. In the method, at least one acceleration data set relating to a vertical acceleration of a motor vehicle, which includes the vehicle battery, is determined. The at least one acceleration data set is then checked for the presence of a predetermined damage criterion, which indicates the potential damage to the vehicle battery. Finally, only for the case that the damage criterion is determined in the at least one acceleration data set, a control signal for actuating an actuator device of the motor vehicle is generated.

A method and a device for determining wheel slip information of an electrically driven wheel of a motor vehicle, according to which during travel, the speed (nE-motor) of an electric motor driving the wheel is detected and the detected speed (nE-motor) of the electric motor is used to determine the wheel slip information.

The invention relates to a sensor arrangement for a motor vehicle, with a pane, a sensor housing, and an optical sensor, wherein the sensor housing is arranged on one side of the pane such that between the sensor housing and the pane, a gap is formed, in which the optical sensor is arranged. To allow for a deicing of the pane in an area of the sensor housing in a particularly simple and thus cost-effective manner, it is provided that between the sensor housing and the side of the pane, a heat conducting element is arranged to conduct heat from outside the sensor housing in between the sensor housing and the pane.

A method for adjusting a zero position of a brake pedal of a brake system of a motor vehicle. A separating valve arranged at least between a main brake cylinder and the respective wheel brakes of the brake system is opened in order to reduce a volume of the brake fluid in a secondary circuit of the brake system. At least one separating valve is then closed again after the volume of the brake fluid of the secondary circuit has been reduced by the predetermined volume amount, and the brake pedal is moved to a new zero position.

A brake system for a motor vehicle. A braking pressure source and at least one wheel brake, which can be impinged by brake pressure provided by the brake pressure source. The brake pressure is provided with at least one pressure piston arranged so that it is linearly displaceable in a pressure cylinder, and with an engine for displacing the pressure piston in the engine which is coupled to pressure piston via a gear. At the same time the gear is provided with force transmission paths which are at least partially parallel to each other and arranged in an operative connection between the engine and the pressure piston.

Brake system for a motor vehicle

A brake system for a motor vehicle has at least a first wheel brake and at least a second wheel brake. A first inlet valve is fluidically connected, on the one hand, to the first wheel brake, and, on the other hand, to a brake pressure source, and a second inlet valve is fluidically connected, on the one hand, to the second wheel brake, and, on the other hand, to the brake pressure source. In this case, a switching valve is provided, which fluidically connects the one fluid outlet of the second inlet valve in a first switching position to the second wheel brake and in a second switching position to the first wheel brake.

A method for influencing the direction of travel of motor vehicles. The motor vehicle has a first steering system, having at least one steering axle with at least two wheels. The wheels are connected to the steering axle through wheel suspensions that can be adjusted by actuators. A redundant steering system is realized by adjusting a steering roll radius of at least one of the steering axles, according to which a force component acting orthogonally to the direction of travel in the region of at least one wheel is applied to the first steering system.

A brake system for a motor vehicle, having a brake pressure source and at least one first wheel brake and at least one second wheel brake, which can be acted on with a brake pressure supplied by the brake pressure source. The first wheel brake is fluidically connected at a first inlet valve and at a first outlet valve, which is fluidically parallel to the first inlet valve, and at a first separating valve via the first inlet valve, and the second wheel brake is fluidically connected at a second inlet valve and at a second outlet valve, which is fluidically parallel to the second inlet valve, and at a second separating valve via the second inlet valve.

A method for haptic feedback on a brake pedal of a motor vehicle. A current stability index describing the current driving situation is compared to a stored critical stability index. A haptic feedback is imprinted on the brake pedal of the motor vehicle when the ratio between the current stability index and the critical stability index exceeds a previously defined limit value.

A motor vehicle includes a first and a second set of two separate hydraulic braking circuits. Each of the two braking circuits of each of the first and second set includes a valve assembly for modulating a braking pressure in the two separate hydraulic braking circuits. A valve unit is arranged downstream of a brake booster and is switchable in response to a malfunction of one or both of the two braking circuits of the first set from a first position in which it connects the valve assembly of the two separate hydraulic braking circuits of the first set to the brake booster, into a second position in which it connects the valve assembly of the two separate hydraulic braking circuits of the second set to the brake booster.
